I am making an eye in 2.8 and came across a problem with shading. Mesh edges reflected the inside and whole thing appeared flat even with smooth shading applied.

Here is the same mesh subdivided 6 times.

Looks bad and has a lot of unnecessary faces. So I used Autosmooth which managed it pretty nicely but still left me with some weird effect where the shadow is cast. I tried changing the size of my lamp with no result.

  • $\begingroup$ Cann't reproduce. If you place just UV sphere near eye - it's looks with the same reflection? Interestion to know how mesh looks and light setup. $\endgroup$

  • $\begingroup$ @Michal, it's displacement on material setup as answered below. imgur.com/R2bZBWf subsurf it 2, with multiply displacement node entry on 0.01 (or disconnected). Just scale down aplitude or use displace modifier after subsurf. $\endgroup$

  • $\begingroup$ @tdhster I've done as you said and the reflection is much better but still a bit distorted. i.imgur.com/GJAcbwF.png $\endgroup$

I think your displacement map is giving this weird pixelated swirls around the eye. Also, why is it connected to an image without a file? Is that how you intended it to be?
